How do you thank a reviewer?

[Mark Young]

Just wanted to find out from other authors and book reviewers how a writer should respond to a posted book review. I am starting to get reviews back on my novel, REVENGE, and want to express to these reviewers my appreciation for their efforts. I try to respond with a thank you email, but what about the posted review itself? Should an author acknowledge on the book review post by saying thank you, for should an author stay in the shadows unless a question is directly ask of the author? What do you do, authors? What would like to see happen, reviewers?

Tagging is changing a lot of that, Stacy. But you have to be friends with the reviewer first. Hopefully, they seek you out first or vice versa.
